Introduction
As a software developer you certainly knew something about collections as an important data type in modern programming languages especially in the .Net Framework 2.0 and above. As you may notice in the .Net Framework 2.0 Microsoft dedicated more efforts to make collection classes reach, intuitive, have good performance, and easy to use as possible. In our tutorial we will talk about Collections in .Net, what they are, how they work, when to use them, and some performance issues.
About Collections
We can define a collection as a set or group of related items or records that can be referred to as a unit. A collection is a kind of data structure; that is a way of storing data in a computer to be manipulated and used in the most efficient way. starts from the base types data structures like primitive types (characters, integers,...), passing by the composite types like (unions), we can finally reach the linear types data structures like (arrays, linked lists, stacks, queues, hash tables, ...) which are the subject of our tutorial.
